When I through out an undead "Ghul" race, I spouted pretty much those same stats. Then I realized it was just a variant goblin. Ultimately though, we've got such a good spread on stats that anything we make is going to be similar to something unless it's uber weak or over powered.

I was talking to my brother and something that occurred to me is that everyone sees an Undead differently, some people think they should be less agile or less end since they are dead and have decaying limbs and body since magic is the only thing holding them together.

Something interesting that crossed my mind was make the undead able to pick which stat they can take to 21-22 at the expense of the other statistics. Maybe have something like 15 int, 14 wis, 12 chr all across the board but has different max stats based on the one that gets perks.
